R700 is a low, mid and high-end chip

There won't be any RV chips anymore, as the entire R7x0 generation is now based on the R700 mini core.It is quite simple, a single core on a single die is low-end, two cores on a single die is mid-range, while four or more cores on a single die is high-end.

ATI will have to put these R700 cores together and we still don't know how they are going to make the chips "talk" to each other; but it will use the same architecture chip but multiplied in the mid and high-end market.

Sounds interesting doesn't it ? It also explains why ATI is pushing so hard for a Quad CrossfireX driver.
